7Claims.- ((1132-33) My invention relates to a new-and improved hair curler.

One of the objects of the invention is to provide a curler having parts which can be assembled at very low cost. 7

Another object of the invention is to provide a curler whose main parts can be made from moldable material, such as a cellulose acetate plastic or other thermoplastic material. The invention includes the use of artificial resins of various kinds such as Bakelite, etc.

Another object of the invention is to provide a device consisting of a minimum number of parts and which will be of durable constuction.

Other objects of the invention will be set forth in the following description and drawing which illustrate preferred embodiments thereof, it being understood that the above statement of the objects of my invention is intended generally to explain the same without limiting it in any manner.

Fig. 1 is a perspective view of the improved device.

Fig. 2 is a longitudinal section through the central axis of the device.

. able member to hold the bobby pin more securely.

Fig. 9 is a detail sectional view of the insert. The device comprises a body member having a shank I, which is integral with a sleeve 2. This body member can be molded from any suitable non-metallic material. All the parts can be made of metal if desired, as the invention is not limited to the use of any particular material.

The turnable member 3 is also preferably made of metal or of any suitable moldable material such as cellulose acetate plastic or the like.

As shown in Fig. 2, the front or free end of the turnable member 3 is provided'with a longitudinal recess 3a. The axis of the recess 3a coin cides, with the longitudinal axis of the member 3.

As shown in Fig. 4, the recess 3a can have a front tapered portion, and a rear portion of substantially cylindrical contour. Intermediate its ends the member 3 is provided with aninteg'ral channeled collar 4, having a shoulder 40. The rear end of the member 3 is imperforate so as to provide an integral cap member I. The member 3 is provided with a longitudinal recess 6, which registers with the longitudinal channel of the 5 collar 4. I

The channel of the collar I is preferably of the same width as the recess 6.

As shown in Fig. 4, the member 3 is thus provided with a longitudinal recess which extends 10 from the .front lateral face of the cap member I almost to the front lateral face lb of the collar 4. The collar is provided with lateral bores 5.

A cap member 8 is also made of suitable resilient material which may be metal, celluloseacetate l5 plastic or the like. This member 8 has a hollow shank 9 which isintegral with a head I0. The

shank 9 is provided with a longitudinal channel. When the parts are assembled as shown in Figs.

1 and 2, the longitudinal channel of the shank 20 8 registers with the recess 6.

The parts of the device can be sold as separate units to be assembled by the user. If the parts are assembled at the factory, the cap member 8 can be connected to the turnable member 3 by 25 suitable adhesive or by suitable mechanical connecting means. When the parts of the device are assembled, there is sufiicient clearance or space inbetween them to insure easy turning of the member 3 in the sleeve 2. 1 30 The clamping bar H which is shown in Fig. 5 is preferably made of resilient metal or other resilient material. This bar II is provided with a pair of depending perforated lugs 12.

As shown in Fig. 3, a pivot pin M has its ends 35 located in the bores 5 of the collar 4, and said pivot pin l4 passes through the perforations of the lugs l2. The clamping bar H is thus pivotally connected to the separated walls of the collar i of the member 3. ,40

the clamping bar H.

As shown in Fig. 2, the end-portion H is provided with an integral depending boss it, which serves to center the spring. IS.

The drawing is substantially to scale and ref- 'erence can be made thereto for further details.

The spring 15 normally maintains the clamping bar II in the full-line position shown in Fig. 2. Upon downwardly pressing theend-portion I 1 against the force of the spring [6, the clamp- 55 ing bar H can be turned to the broken-line position illustrated in Fig. 2.

After the members 3 and II have been assembled, the rear end-portion of themember 3 can be pushed through the sleeve,2.'while the end-portion I1 is depressed and the bar II is held in the broken-line position shown in Fig. 2.

In the full-line position oi member II which is shown in Fig. 2, the member I! would be too high to permit the same to be pushed through the sleeve 2. 'I'he member II has a relatively depressed portion Ila between its clamping body and the end-portion II. This depressed. portion Fla is reinforced by a stamped-out rib.

The bore of sleeve 2 is wider at its front end than at its rear end, so as to provide a shoulder S. This provides a clearance at the front end of sleeve 2. This clearance and the recess 3 and the cut-out shape of collar 4 make it possible to turn member II from the full-line to the brokenline position.

The sleeve 2 serves as a bearing in which the member 3 can be turned about its longitudinal axis.

After the members 3 and II have been thus assembled with the body of the device, the member 8 is moved into and secured in the position shown in Fig. 2, thus preventing any substantial left-hand movement of the member 3 relative to the body of the device, because the end wall-of the shank 9 then substantially abuts the rear lateral wall of the shank clearance for easy turning.

When the parts are assembled, the rear or right-hand lateral end-wall of the collar 4 abuts the shoulder S which is provided in the interior of the sleeve 2, to limit the movement of member 3 relative to the body in the right-hand direction. A hair pin or bobby pin H can be inserted in the position shown in Figs. 1 and 2 so that one of the shanks of said hair pin is held releasably within the recess la of the member I and the other shank is located in recess 3a.

The hair pin H can be readily pulled out of the curler.

The shanks of the resilient metal bobby pin H are moved apart from their normal positions, in order to insert said shanks into the device, in the position shown in Fig. 2. Hence, when the bobby I, leaving enough pin is in said position, it is retained, in the curler by the resilience of said shanks. One end of the lock of hair is clamped between the member 3 and the member I, after the shanks of the bobby pin have been inserted into recesses la and 3a. The member 3 is then turned, without turning the hair pin, so as to wind the lock of hair spirally or helically around the member 3.

The clamping member II is then moved to the broken-line position shown in Fig; 2, so as to release the curl, and the curl is then pushed longitudinally into the broken-line end-position shown in Fig. 1, so that one of the shanks of the hair' pin enters said curl and the other shank remains external to the curl. The curl and the hair pin are then removed from the device, so that the resilient shanks of the hair pin clamp the curl, so that the device can then be used with another hair pin for making another curl.

Fig. 9 shows an insert 25 having a collar 26 which may be made of metal or any other suitable material. A ferrule 21 is assembled with the collar 26, so that the ferrule 21 can be turned freely relative to the collar 26. The ferrule 21 has a head 28 whose diameter is greater than the internal diameter of the collar 26 and w ich is less than the external diameter of the collar 26. The ferrule 21 is provided with a throughand-through bore which also extends through the head 28. The collar 26 has a drive-fit in the enlargement 3b of therecess 3a, which is shown in Fig. 8. Therefore the collar 23 and the member 21 can be assembled and the collar 26 can be forced into the recess 3b, until the front end of the collar 26 is flush with the front end of the member 3. The length of the recess 3b is greater than the length of the ferrule 21, so that there is a clearance between the head 22 and the inner lateral wall of the recess 31).

The axis of the bore coincides with the axis of the recess 3a.. The shank of the bobby pin is passed through the bore 29 to enter the recess 3a.

The tip of the shank may abut the inner lateral wall of the recess 3a. The lateral diameter of the recess 30 is greater than the lateral diameter of the bore 29. This construction causes the resilient shank of the hair pin to be bent temporarily out of its normal shape when said shank is thus inserted through the bore 29 into the recess 3a. This aids in preventing said shank from springing out of the member 3, when said member 3 is turned relative to the bobby pin and to the body of the device. When the member 3 is turned, the collar 26 turns in unison therewith, but the ferrule 21 does not turn. In the embodiment shown in Fig. 4, the tapered shape of the front end of recess 3a also causes the resilient metal shank of the hair pin to be bent temporarily out of normal shape, when the shank of the hair pin is pushed into the cylindrical inner part of recess 3a. This acts to prevent 'the hair pin fromspringlng out of the device,

when member 3 is turned relative to the hair pin. The shank of the hair fits fairly snugly in the rear portion of shank 3a, in Fig. 4. If the diameter of the shank is one-sixteenth of an inch, the cylindrical portion, of recess 30 may have a diameter of flve sixty-fourths (96 of an inch.

While I have shown a preferred embodiment of the invention, numerous and very substantial changes can be made without departing from its spirit.

Likewise the invention covers numerous valuable sub-combinations which are not operative per se and which can be used in many difl'erent forms of curlers.

It will be noted that the construction above specified makes it possible to apply the turnable member 3 and the clamping member II as a sub-unit to the body of the device, and to remove the members 3 and II as a sub-unit from said body.
